When you’ve got lots of post meta-boxes, your post edit screen can become difficult to search. Make your post edit screen easier to navigate and manage by creating a set of tabs, with the Tabify Edit Screen plugin. And manage it all from the WordPress back-end!
There are still lots of things changing in the code base. There are some hooks you can use but they can change from implementation till 1.0. I will always try to maintain backwards-compatible but till 1.0 I can’t be sure for that.

Tabify Edit Screen

If you have really a lot of custom meta boxes in your post type, this plugin is perfect to organise it. Looks great, and easily integrated. 

Perfect for organising lots of fields

This plugin is hot sauce. For websites with lots of custom fields and metaboxes, this is a game-changer for UX.

Answer to my prayers

Enable tabs in the edit screen and manage them from the back-end.
